Definitions

  • This invention relates to a prefabricated structure, particularly for use in the building industry, comprising a framework of welded steel wires, supporting a panel in lightweight material.
  • a prefabricated structure is known from the French patent 1 374 926 which comprises a panel of lightweight material and two trellises perpendicular to the larger surfaces of the panel, wherein each trellis includes a reference longitudinal wire parallel to said larger surfaces, separating wires welded to the reference longitudinal wire and first arrest elements for engaging the panel.
  • the panel is disposed in front of a second panel to define a void used as form for a concrete casting.
  • the two panels have large dimensions and are held at their given positions by two trellises located at two terminal edges of the panels. Each trellis is connected only with the two panels and is provided with a projection to be engaged with the void of an overposed structure of the same type.
  • a further disadvantage of the known structure is given by the fact that the panels do not enable a sufficient adhesion to the setting of plaster on the external surfaces of the prefabricated structure.
  • the technical problem of the present invention is to provide a prefabricated structure of supported or supporting type which can be implemented and put in operation easily and reliably, using unskilled personnel in the erecting yard, and which enables an easy setting of plaster in the structure.
  • each trellis comprises various orders of separating wires and a first and a second external longitudinal wire welded to the various orders of separating wires to the external of the space included between the arrest elements and the reference longitudinal wires, wherein the transversal wires cause the separating wires of a same order of the various trellises to be coplanar and wherein the said panel is formed by a group of adjacent elongated sections wherein each section is inserted in the spaces defined by the first arrest elements, the reference longitudinal wires and two adjacent separating wires of said trellises.
  • the prefabricated structure comprises a three-dimensional framework 9 made of metallic welded wires, and at least one panel 15, in lightweight heat-insulating material, placed parallel to the largest surfaces 6 of the structure 9a, 9b.
  • the framework 9 comprises a series of trellises 8, identical to each other, essentially flat and in the form of a greatly elongated rectangle.
  • the trellises 8 are placed one in front of the other, perpendicular to the two surfaces 6, and are kept firmly in their respective positions by means of a double series of transverse wires 7.
  • the trellises 8 will be vertical, while the transverse wires 7 are horizontal and adjacent to the largest surfaces 6 of the structure 9a, 9b.
  • Two layers of plaster 16 cover the wires 7, forming the two largest surfaces 6 of the structure 9a, 9b.
  • the prefabricated structure with a single panel 15, denoted by 9a is used to form partition and floors and the prefabricated structure with two insulating panels 15, denoted by 9b (Figs. 3, and 10), is used to form supporting walls of the building under construction.
  • Each trellis 8 is obtained by welding together a pair of longitudinal and parallel wires 1 (vertical when the structure is in use) with separating wires 5 in such a way as to form a small staircase with steps of a constant width and pitch. Between the longitudinal wires 1 and a short way away from them, equal to the thickness of the plaster, the trellises 8 include other longitudinal wires 3 parallel to the wires 1 and also welded to the separating wires 5. The welding is carried out electrically at certain points, resting the trellises 8 on a magnetized plate provided with gauges. The length of the wires 1, 5 and 7 is equal respectively to the height, the thickness and the width of the prefabricated structure 9a, 9b. The transverse wires 7 are welded to the longitudinal wires and produce a lightweight, stable framework in which the separating wires of a similar sequence of step prove to be in the same plane as, and perpendicular to, the planes of the wires 1 and 3.
  • the diameter of the wires is 2,2 mm.
  • the height of the structure lies within the range 2,60-3,50 mm and its width is 1,20 m; the thickness is approximately 0,10 m for structures 9a, 9b and approximately 0,15-0,30 m for structures 9b; the trellis 8 have an interval of approximately 0,10 m and the pitch of the transverse wires 7 is approximately 0,07 m; the pitch of the separating wires 5 is approximately 0,15 m and the distance between the wires 1 and the wires 3 is approximately 0,04 m. It is obvious that these values are purely illustrative and may vary according to the particular requirements of the construction.
  • the panels 15 can be made of various cellular material such as polyurethane foam, polystyrene and PVC of medium density, or of fibrous materials such as fiberglass; or of lamellate materials,or of a mixture of materials. In short, in specific case the material may even be non- insulating or non-metallic.
  • the panels 15 are subdivided into parallelepiped lumps 2 of a definite thickness and height, respectively 0,04 and 0,15 m in the given example.
  • the parallelepiped space in rectangular section defined by the two pairs of wires 5 and 3 of each sequence of trellises 8 is occupied by corresponding lumps of lightweight material 2 and its section is essentially equal to the available space, and its length equal to the width of the structure 9a.
  • the individual parallelepipeds 2 are inserted in the corresponding spaces between the wires 3 and 5. This is made possible by the compliance of the parallelepipeds 2 and of the wires 3 and 5.
  • the structure is ready to put into operation, lacking only the plaster for re-covering the space between the wires 1 and 3. Wires 3 hold the lumps 2 in place between the surfaces 16 of the structure and correctly aligned with each other.
  • the trellises 8 comprise, besides wires 1 and 3, two further longitudinal wires 4, welded to the separating wires 5 and placed between wires 3 parallel with these same wires 1 and 3, which provide stops for the two panels 15.
  • the separating wires 5 of an identical sequence of steps to trellises 8, together with the two pairs of wires 3 and 4 define two parallelepiped spaces in rectangular section for the whole width of the framework itself. These spaces are occupied by lumps 2 inserted as in the framework of structure 9a.
  • the structure 9b proves to be composed of a three-dimensional metallic framework with two panels in lightweight material separated by a void 17. This void may ve filled directly by a casting of concrete 18 whose form is determined by the panels 15 implemented with the lumps 2 (Fig. 9).
  • the concrete 18 makes it possible to use the structure 9a as a supporting structure for other parts of the building and renders simple the integration with other horizontal or vertical structures in the building. Moreover the resistance of structure 9b to the various stresses can be improved by inserting in the void 17 a framework of vertical 19 or horizontal 23 bars.
  • the resistant concrete sections 18 and therefore the distance between the panels 15, the number and the section of the bars 19 and 23 are determined by the designer of the building with the usual rules for reinforced concrete and, as a precaution, the contribution of the framework 9 of the structure 9b is not taken into account.
  • the prefabricated structures 9a, 9b may be modified in the builder's yard using saw and shears to adapt it to particular requirements of the building.
  • one of the two panels 15 in structure 9b may be interrupted to allow space for a concrete pillar 32 (Fig. 11), which will be of a piece with the concrete 18 which fills the void 17.
  • a structure 9c (Fig. 2) consists simply of a framework of longitudinal wires 40, of short spacing wires 41 and of transverse wires 42. This structure is particularly adapted to strengthening work and as support for plaster during restoration work.
  • the structures with a single panel 15 may have a simplified form 9d with only three longitudinal wires for each trellis, when the plastering of one of the sides of the structure itself is of no importance. I.e., one of the two wires 3 is eliminated.
  • the structures with a single panel may also take the form denoted by 9e, in which the lightweight material consists of large parallelepipeds 43 which give the structure an increased thickness indispensable for its use as a floor.
  • some 9b structures have one side modified to form the walls of a corner.
  • a terminal trellis 44 has a single series of rectangular sections, the panels 15 have their edges bent at an angle of 45° and the edge of one panel juts beyond the other by an amount equal to the thickness of the panel 15.
  • This variant permits the simple formation of a supporting corner wall, using two of these structures reversed.
  • Two series of small steel rods 39 sunk in the block of concrete 18 ensure the necessary resistance at the corner structure, together with other linking components 45 of the adjoining wires 1.
  • Some linking components of a particulartype permit an outstanding utilisation of structures 9a and 9b, both in mutual links and in links with other structures in the building.
  • the horizontal junction between two structures 9a and 9b is achieved with steel straps 12 inserted between the wires 1 and 3 on both sides of the structure (Fig. 4 and 10) and their extremities engage with the parts ofthetwo wires 5 which protrude from the panels 15.
  • the straps are then covered with plaster 16.
  • the straps 12 are corrugated and have sawn edges.
  • the joining of the structures 9a, 9b and 9c and the horizontal structures of the building is reinforced by means of simple short shaft 46 of improved adhesion, of steel rods 28 (Fig. 6) in a U-shape, of angle iron, and of reinforcing components 30 made of welded wires (Fig. 5), these too being angled.
  • the components 30 comprise three steel rods 21, 20 and 22 parallel to each other and placed in correspondence with the vertex and the extremities of the arms of the L-shaped section via the wires 25 bent into an L or via a pair of wires in a sinuous pattern welded respectively between the end rod 20 and the vertex rod 21, and between the rod 21 and the other rod 22.
  • a foundation 48 (Fig. 7) of reinforced concrete is used and care must be taken to insert the short shafts 46 in the areas where the panels 9b will be inserted and allowing the shafts 46 to protrude from the surface of the foundation.
  • the structure 9b are then rested on the foundation in such a way that the void runs across the shafts 46 and that the sides of the various structures match.
  • the structures are joined together with the rods 12 and reinforcing components 30 are placed on top of them, if necessary inserted between the lump 2 and the wire 1 (Fig. 9). Finally, the concrete casting is used in the void 17.
  • structures 9e are used, of half the normal width (0,60 m in the preceding example), and they are reinforced at the edges by means of an angle-iron 47 (Fig. 8), used in pairs, to form an inverted T-shaped beam which meets the adjoining edges ofthetwo structures 9e.
  • an angle-iron 47 Fig. 8
  • the wire 5 which protrudes below the last parallelepiped 43 is cut and the lowest edge of the same parallelepiped 43 is bevelled.
  • one side- of the angle-iron is inserted between the parallelepiped 43 and the wire 1. More components of the same kind are rested on the supporting structures of the building and converge to form the floor of the desired width. The whole may be inserted in the concrete 18 which is retained by the two wings of the inverted T in the areas of the links between the two half-structures 9e.
  • the procedure is as denoted by Fig. 9, inserting the rods 28 which are U-shaped across the transverse wires 5 and uniting the whole by means of a casting of concrete.
  • rods 19 and 23 and the reinforcing component 30 were inserted and horizontal beams were implemented, using a lump 2 of specific thickness instead of a parallelepiped for the bearing part of the floor.
  • the hollow part was used as a form for the beam of reinforced concrete 49 with the rods 23.
  • the prefabricated structure of the invention makes possible the implementation of buildings in a simple and inexpensive manner, using generic workers.
  • the individual structures will prove light and easily transportable.
  • the structure will prove very strong and will have excellent heat-insulation characteristics. It is also suitable for use in seismic zones.
